Hello!
This is real simple!
So let's look at your first ordered pair, (-2,0)
-2 is the x-coordinate, 0 is the y-coordinate. 0 is the origin - or the center - of your graph. Don't put a point yet!
Next, -2 is to the left, so look for -2 on your graph (or count two to the left) Now put a point there. You have plotted (-2,0) on your graph!
Let's try another.
(0,4)
Look at 0 on your graph. The 4 is the y-coordinate, indicating that you'll go up on the y-axis.
Go up 4 on your y-axis
Put a point, you plotted (0,4)
One more?
(2,0)
x. y
Go to positive 2 on your x-axis (since it is the x-coordinate). Notice the y-coordinate is 0, you don't need to go up! Plot your point
You plotted (2,0)
I hope I helped. Please ask if you still need help.
